I am having the same issue with a Dell Mini 10 (Model 1011), Atom N230 and GMA 945. I successfully, and without any effort, had Compiz enabled while driving both the LVDS at 1024x576 and the VGA at 1024x768 right of LVDS in 9.04. Today I upgraded to 9.10 via update manager and now have this same issue. Combined width is 2048 which is the max texture size (width) for the 945 chipset. This may not be a bug, but is most definitely a regression because I have lost functionality over a previous version. As mentioned in the other bug, success can be had by arranging the screens vertically: 1. Switch to Metacity (Desktop Effects set to None) 2. Attach external monitor 3. Open Display Settings 4. Arrange external Below LVDS 5. Set proper screen size for the VGA (in my case it's actually 1280x1024) 6. Turn Compiz back on (Desktop Effects set to Extra) This arrangement nets a virtual resolution of 1280 x 1792 which falls neatly inside of the accelerated buffer limit of 2048x2048 on the 945. The problem is, as mentioned, this is a regression from 9.04 (which did let me arrange them side by side) and is spatially difficult to maintain as I don't rest my netbook on top of my monitor as the arrangement seems to make me want to feel. -- [i945gm] [karmic] X servers hangs when settings up dual monitor config https://bugs.launchpad.net/bugs/438000 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
